Original Abstract

This paper deals with the simulation of mechanical vibration using Ansoft Maxwell programs and Ansys Workbench. The actual vibrations are among the compelling indicator of failures of electrical machines. Any mechanical failure or fault in the electric or magnetic circuit affects the individual components of the vibration. Thanks to program Maxwell is then possible to simulate electromagnetic field and distribution of radial forces within the asynchronous motor. Changes of radial forces then enters to the Ansys Workbench as a boundary condition for structural analysis. On that basis, you can watch the size, direction and frequency of the vibration of the machine. This procedure may be used for simulating the impact of any defects on the vibration spectrum. In practice it is possible to use, for example to simulate a breaking of rotor bars and the influence of their break. This method can be used for the calculation of the influence of disturbances on any number of these bars. Other common disorders are static and dynamic eccentricity. Through the use of interconnection program Ansys and Maxwell is possible to determine the course and amplitude of vibration given to size eccentricity . This information can help to monitor the development of faults in electrical machines, their identification and determination of their range.
